The Science Behind Collagen Induction Therapy

Microneedling creates controlled micro-injuries at precise depths (see diagram below). This triggers the body's natural wound healing process, stimulating:

• Collagen production (Type I & III)

• Angiogenesis (new blood vessel formation)

Clinical studies show optimal results occur when treatments are spaced 4-6 weeks apart, allowing complete skin remodeling cycles.
